The Eleventh Five-Year Plan (2006-2010) is listed as the 11th Five-Year Plan of New China, but strictly speaking, in the sense of "planning", it should be counted as "the first". Because, before ten, all are "five year plan". The transformation from planning to planning has also become another historical coordinate in the process of transformation from planned economy to market economy.

2010 is the last year of the 11th Five-Year Plan. According to the official data, China's GDP growth rate from 2006 to 2008 was 11.6%, 13% and 9.6% respectively. In 2009, despite the severe impact of the global financial crisis, the GDP growth rate was still as high as 9.1% due to the effective macro-control policies and measures of the central government. China's GDP grew by 10.3% year on year in 2010. The grand goal of building a well-off society in an all-round way got off to a good start.

Review of the development of unsaturated polyester resin industry in China during the eleventh five-year plan
According to the statistics of China Composites Industry Association (including the output of resin manufacturers of non-member units), during the "11th Five-Year Plan" period, the output of unsaturated polyester resin in China increased from 850,000 tons in 2005 to 1.5 million tons in 2010 (estimated), with an average annual growth of 12.4%. Although affected by the global financial crisis, but because the central government to expand domestic demand, strengthen infrastructure construction issued the "four trillion yuan investment plan" and "ten industry revitalization plan", so that permeated into the national economy in all areas of the composite material industry benefited a lot, the resin industry quickly recovered growth. It can be said that the five years of the "eleventh five-year plan" is the fastest and best period for the development of China's unsaturated polyester resin industry in the past 40 years since its establishment in the mid-1960s.

During the "Eleventh Five-Year Plan" period, the development of China's unsaturated polyester resin industry presented four characteristics:
1. The capacity and output have increased greatly, and the product structure has been continuously optimized
* The start-up of large-scale domestic demand and the continuous growth of export have brought a huge market space to the FRP composite industry, and the demand for unsaturated polyester resin has increased greatly. The capacity and output of China's unsaturated polyester resin industry have increased rapidly.
* Independent innovation of glass fiber reinforced plastic composite molding technology upgrading, promote the quality of unsaturated polyester resin products, structure optimization. Due to the development and improvement of China's FRP equipment manufacturing industry, the SMC/BMC mold pressing, winding, pultrusion and other equipment and mold design and manufacturing technology level of Jiangsu, Zhejiang, Hebei, Shandong and other provinces is becoming more and more mature, not only to meet the domestic demand, but also batch export. The development of equipment manufacturing industry has promoted the popularization of mechanized forming technology of FRP composites. In 2009, China's fiber winding tube can production line, centrifugal casting pipeline production line, pultrusion process, SMC/BMC molding process, continuous light plate production line, vacuum introduction process and RTM process and other mechanized forming process has accounted for 66% of the whole FRP composite forming process, the proportion of hand paste forming process has decreased greatly.
* In line with the industrial development, under the organization of China Composite Materials Industry Association, the National Technical Committee for Standardization of Fiber Reinforcement formulated the industrial standard of "Unsaturated Polyester Resin for Mechanical Forming of Fiber-Reinforced Plastics (JC/T1092-2008)" in time, which was implemented on December 1, 2008. The implementation of the standard standardizes the technical standard of unsaturated polyester resin for mechanization molding and promotes the optimization of product structure in the unsaturated polyester resin industry.
2. The consumption of casting type unsaturated polyester resin reinforced by functional fillers increases rapidly
During the period of "11th five-year plan", be faced with polyester handicraft contraction in the international market situation, many companies quickly turned to architectural decoration in domestic and foreign markets, casting artificial stone, stone and quartz industry rapid rise, and gradually mature and improve technology, the veneer to mechanized production lines from mill molding, products widely used in ambry panel, metope adornment and ground material. Fujian, Guangdong some economic strength of stone, ceramic tile, floor tile production enterprises also invested heavily to the quartz stone industry. According to statistics, in 2010, the national functional filler enhanced casting with unsaturated polyester resin consumption of about 550,000 tons, accounting for this year's national total consumption of 36.7% of unsaturated polyester resin.

3. The MW grade FRP wind turbine blade has become another major product in China's composite material industry after FRP sand pipe, promoting the technological innovation of unsaturated polyester resin and epoxy vinyl resin
The requirement of high performance resin for megawatt grade FRP wind turbine blades accelerates the technological innovation of unsaturated polyester resin and epoxy vinyl resin in China. The domestic megawatt wind power market has entered a period of rapid development since 2007, with an annual average new installed capacity of more than 6 million KW. In 2009, the new installed capacity of 12 million KW (equivalent to 8,000 sets of 1.5MW blades), 160,000 tons of composite materials, and more than 50,000 tons of resin (including the hood). Unsaturated polyester resin and epoxy vinyl resin account for about 50%.
China's megawatt grade FRP wind turbine blade patent technology is mostly introduced from Germany and the Netherlands, blade shape design, structure design, layup design, material design, mold technology to blade manufacturing is a system engineering, has specific requirements for fiber and resin, and has been certified by German classification society GL. Domestic research and development ability resin enterprise would have developed to replace imported epoxy vinyl resin and unsaturated polyester resin in production in a foreign capital enterprise, only the wind power blade manufacturer factory feel hesitate to choose the domestic resin manufacturer of resin, so as to make the foreign companies, domestic FRP wind-power blades market first. But with glass fiber reinforced plastic wind blade manufacturer for the introduction of technology digestion and absorption, and the blade design and manufacturing technology has been introduced from single to independent research and development, sinoma wind, boosted by even the, baoding HuiTeng, Shanghai FRP research institute and other key enterprises have the following 3 mw blade independent research and development ability, as long as there is a research and development ability of resin enterprise unremitting efforts, This kind of foreign resin enterprise monopoly wind power blade market pattern will be broken eventually.
4, unsaturated polyester resin industry integration and reorganization has begun to appear
According to incomplete statistics, at present, there are about 180 large and small unsaturated polyester resin manufacturers in China, with uneven technical levels and great differences in production capacity. The annual production capacity of small unsaturated polyester resin manufacturers is only several thousand tons, while the annual output of large unsaturated polyester resin manufacturers is more than one hundred thousand tons. Small manufacturers with simple equipment, backward production process control means and unstable product quality can only produce low-end universal resin. Manufacturers with more than 30,000 tons of capacity have relatively excellent equipment, advanced production process control means and stable product quality. Among them, Jinling DSM Resin Co., Ltd., Jiangsu Fuling Chemical Co., Ltd., Ashland Company and Huachang Polymer Co., Ltd., East China University of Science and Technology have adopted DCS control to realize automatic control of the whole process of the production of unsaturated polyester resin.

Enterprise management level is also good and bad are intermingled, in general, small scale of unsaturated polyester resin production factory is a private, individual enterprises, the basic management level, poor organization is not sound, environmental protection and safety in production inputs, rarely occurring in the process of production is basically secretly emissions, wastewater emission almost directly without any processing means; However, the factory with capacity of more than 30,000 tons has a relatively high management level. The waste water generated in the production process is incinerated in an incinerator to achieve "zero discharge" of waste water. The exhaust gas adopts advanced purification treatment equipment; Moreover, several large resin companies have adopted ERP system for production, finance, procurement and sales management.
Jiangsu, Zhejiang and Shanghai are the concentrated areas of the unsaturated polyester resin industry in China, leading the domestic market of unsaturated polyester resin and FRP composites by technological innovation and new product development, and promoting the development and improvement of the domestic unsaturated polyester resin industry and FRP composites. In 2010, the output of unsaturated polyester resin in these three provinces and cities accounted for more than half of the total output of the country, and 95% of the national vinyl resin output was concentrated in Jiangsu and Shanghai. Famous unsaturated polyester resin manufacturers both at home and abroad are gathered in this area, including foreign (Taiwan) enterprises such as Jinling DSM, Huari New Products, Changxing, Ashland, Showa and Shangwei, which entered the Chinese market earlier. There are also a number of domestic enterprises with independent intellectual property rights, such as Shanghai Huachang, Tianma Ruisheng, Jiangsu Fuling, Changzhou Xinri Chemical (namely Yabang), Tianhe (Shanghai, Zhejiang Linhai and Jiangsu Nantong each have factories), Huake, China Resources, Xinhe and so on.
Guangdong is also a big province in resin production and consumption. Foton, Huaxun and Chenbao are all enterprises with large scale.
However, at the same time, environmental pollution has become an embarrassing companion in the development of China's unsaturated polyester resin industry. Many small resin factories without environmental protection facilities have produced stealth-discharged waste water and direct discharge of waste gas, which have caused very serious environmental pollution. Jiangsu province has clearly stipulated that all chemical plants (including unsaturated polyester resin plants) must be relocated to the chemical industrial park in the provincial development zone within a certain period of time. The new plant area is subject to strict safety, environmental, energy and water evaluation, and those chemical enterprises that cannot afford to relocate will be shut down. Changzhou Xinri Chemical (i.e. Yabang), Jiangsu Fuling and Tianma Ruisheng have successively moved to chemical industrial parks in provincial development zones in their respective regions. Changzhou Huari and Huake are building new factories. Jinling DSM is also moving. Other provinces and cities will follow suit. Therefore, many small and medium-sized resin factories will choose to close because of high relocation costs.

II. Prospects for the development of unsaturated polyester resin industry in China during the 12th Five-Year Plan period

During the "12th Five-Year Plan" period from 2011 to 2015, China's composite material market will further become the focus of the world's attention. It is widely believed that China is still the world's fastest growing economy and the largest composite material market in the world. This can be seen in the decision by the board of directors of Rakode Corporation to increase its investment in Tianjin, China. In 2009, they had a comprehensive understanding of China's composite material market and customers' demands, and decided to increase the investment from 130 million yuan to 300 million yuan, with a capacity of 30,000 tons in the first phase and 50,000 tons in the second phase.
In 2009, the global output of composite materials was 9 million tons. China's output of 3.23 million tons surpassed that of Germany and Japan, ranking second in the world, accounting for 35.88% of the world's total output. In 2013, China will account for 43 per cent of the world's total composite production, according to JCC Group forecasts.
On September 8, 2010 the State Council approved a has important directive significance of document, "state council on speeding up the decision of the cultivating and developing strategic emerging industries", selected the energy conservation and environmental protection, a new generation of information technology, biology, high-end equipment manufacturing, new energy, new materials and new energy automotive industry as a strategic emerging industry of seven, What is particularly striking is that the decision for the first time singles out new materials as a strategic emerging industry. It is obvious that China's composite material industry, which is an important part of the new material field and has penetrated into the other six fields, will usher in unprecedented opportunities for development.
Looking forward to the "12th Five-Year Plan", according to the information and analysis we have learned, the development of China's unsaturated polyester resin industry is predicted to have the following trends:
1. Unsaturated polyester resin industry deepened integration and reorganization, from the "Spring and Autumn Period" to the "Warring States Period"
* 180 unsaturated polyester resin production enterprises at present, there are at least two thirds belongs to small scale, backward technology, lack of talents, shortage of funds, serious pollution of small businesses, due to an inability to move into the development of chemical industrial park by the government shut down or choose in enterprise to have the size of the resin, unsaturated polyester resin manufacturers will reduce the number of, Production capacity to large factories, the entire industry to intensive, scientific and technological transformation.
* Unsaturated polyester resin plants with an annual output of more than 30,000 tons are the backbone of China's unsaturated polyester resin industry, but they are still small compared with those in Europe and the United States. There will be two development modes: one is to greatly expand the production capacity, to the annual output of 300,000 to 500,000 tons of aircraft carrier resin enterprises stride forward, dominating the general resin market; Second, to develop emerging markets, research and development of marketable, high-tech content, high added value of new varieties to lead the high-end resin market.
2. Green and low-carbon economy has opened up a broad market for composite materials and unsaturated polyester resin industry
After nearly fifty years of market tests, glass fiber reinforced plastic composite materials (mainly unsaturated polyester resin matrix composite materials) for its excellent properties, such as design, high modulus than strength, excellent electrical performance, chemical corrosion resistance, aging resistance, water resistance and flame retardant performance has been proved that it is irreplaceable by other materials materials and structural materials. During the 12th Five-Year Plan period, FRP composites will become an important leading material for the low carbon economy.
* The core of low carbon is energy conservation and emission reduction. Large power plant flue gas desulfurization equipment, petrochemical anticorrosion engineering and municipal water diversion engineering need a large number of FRP composites. It is estimated that by the end of the 12th Five-Year Plan, the composite materials used in the power industry alone will reach 1.2 million tons. Among them, large power plant flue gas desulfurization equipment for vinyl resin requirements are very high, not only requires resin corrosion resistance, abrasion resistance, high thermal deformation temperature, but also requires high tensile strength, tensile modulus and elongation at break. At present, the imported Dow D411 mainly occupies this market, (Ashland Changzhou plant has been able to produce after Ashland acquired Dow vinyl), ATLAC430 of Jinling DSM, SW901 of Shangwei and MFE-2 of Huachang also have a certain market share. In the face of such a huge market, although the technical difficulty is very big, domestic resin enterprises also have to spend great efforts to develop this kind of tree grease.
